This weekend, we went to walk the Flumserberg Alpenblumenweg (or flower trail). I got to see a lot of flowers I hadn't seen before along with some stunning views of the mountains in the area.
One of the mountains is called the Sichelkammfalte (or Sichelkamm fold). The formation of the fold took 5 million years. Here is a picture of it and of other folds in a mountain nearby.
